To all whom'z't may concern: I

Be it known that I, Mnrrmno THOMSON,

a subject of the King. of Great Britain, residin at Red Bank, in thecounty of Monand State of New Jersey, have invented certain new anduseful Improvements in Sofa-Bedsteads, of whichthe following is aspecification.

10 in sofa bed steads' and the object of the This invention relates toan improvement presentinvention is the provision of; an

improved device of this character in which the bed sections are of alength to form a bed o f standard length and are withal so constructedand arranged as to foldwit-hin the body-of a sofa of. normal width andlength.

A further object of the invention is the provision of a sanitary deviceof this character, all of the parts being so constructed and arrangedthat ready access may be had thereto for the purpose of cleaning thesame.

A further object of the invention *is the provision of a simple andefiicient device of this character, the parts of which may be readilybrought into position to form a bid, when desired, and may be readilyrestored to their normal positions to form the sofa. w

A further object of the invention is the provision of a device of thischaracter,'the head section of which may be supported at various anglesrelative to the other bed sections.

Other objects of the invention will be apparent from the detaileddescription hereinafter, when read in connection with the accompanyingdrawings forming a part hereof. wherein a convenient embodiment of theinvention is illustrated and wherein like charm-tersof reference referto similar parts in the several views.

In the drawings: Figure 1 is a perspective view of the device folded toform a sofa;

Fig. 2 is a perspective view of the carriage removed from the main frameof the sofa bedstead; Fig. 3 is a cross section of the device whenfolded, parts being shown in elevation; Fig. 4 is-a section taken online 4-4 of Fig. 3, and Fig. 5 is aside elevation showing the device inits extended position, parts being shown in sect1on.

Referrin now more particularly to the drsstwings; designates the mainframe of the device which is conveniently formed of metal and'comprisesside piece'sfo a which will constitute the front of the sofa.

are connected in suitable manner and which constitute the side frames ofthe sofa; Secured to the inner portions of the sides a a of the mainframe adjacent the lower ends thereof are horizontally disposed runwaysa which are. conveniently tanned of channel iron, the outer range or"the channel iron. forming one ct d. runways being providcd with apiuruf" oi notches Satin the edge-thereafter a purpose to hehereinzrfiter more particularly set forth. l ositioned ,between the sidepieces a o of the main irgime A is a carriage, B which is convenientlyin the form of an open frame formed of angle iron or other suitablematerial. The earriage B is provided adjacent the rear end thereof witha pair oi rollers 12 which are adapted to run in the guide ways a asecured to' the lower portions of the side pieces a a of the mainframeA. Secured to the front endoi-the carriage B is a panel of wood ,orother suitable material B" and mirrnaim rnom'son, or BANK, :rswsnnssr.

mounted in the lower portion of said panel are a plurality of casters 6which are adapted to rest directly upon the floor and support theforward portion of the curriag ge ii. In the normal position of thecarriage, the panel B will lie between the front edges of the sidepieces a a of the main frame and From the construction just described,however it will be noted that the carriage may be moved outwardly on therollers 15 Z) and casters 1) Z) to occupy a position in front/0t themain frame A of the device. Pivotally secured in any desired manner tothe rear portion of the carriage B is, a pawl 12 which is adapted toride over the edge of the guide ways a .in which are formed the notchesa the pawl being adapted to engage said notches as the carriage is drawnoutwardly so that the carriage may be held in any desired position. Tooperate the pawl 6 a suitable cord b which extends from the lpawl oversuitable guides to the front portion of the carriage b, so that the endthereof is readily accessible for manipulation when .it is desired towithdraw the pawl b from engagement with the notches a einthe guideways, as is clearly-shown in Figs l and 2;

Supported directly upon the'uppered vof the sides of the carriage Bis aseatin C 'said' frame conveniently comprisingtubu-lar end piecesc c anda frame 'cof angle iii iron which is bolted to said tubular end pieces.'Supported by said frame r is a sprin fabric 1;" which constitutes. whenthe said rame is in normal position, the seat of the sofa. Secured tothe underside of the seat frame C and normally positioned between theside walls of the carriage B is a bed section I) which is convenientlyformed of a frame (Z of angle bars, the ends of which are bolted orotherwise secured to the tubular cross pieces c of the seatframe (,3.Carried by the frame (I of the bed section D is a spring fabric rl ofany suitable type. The seat frame 0 is pirotally connected at itsforward edge to the forward edge of the carriage B by suitable hinges sothat the seat frame may he swung to a horizontal position in front ofthe carriage B, which will bring the bed section D carried by said seatframe to a horizontal position with the" sprin fabric ll thereofuppermost The seat fi-auie C is adapted to be held in this position bysuitable legs 0 which are pivotally secured to the inner surface of the.rear wall of the frame a. When not in use, the'legs arefolded to lieflat against the rear wall of the frame 0 of the seat frame 0, so thatwhen said seat frame is returned to its normal position, the legs willbe concealcd by the usual seat cushion which is adapted to bepositionedupon the top of the spring fabric c'of the seat frame C.

E designates a supplemental bed se tion which is normally positionedwithin the open frame. of the carriage B. The supplemental bed sectioncomprises a frame c convenient l v formed of angle bars and tubularcross bars 1'." e bolted or otherwise secured to the ends of said frame,said cross bars being of such a length-that the ends thereof project fora slight distance beyond the sid bars of the frame cgof the bed section.The frame I: of the bed section I!) is provided with a spring fabric (10f any suitable character upon .of any suitable character. Pivotallysecured which is adapted to be positioned a mattress to the forwardportions of the side bars of the frame of the bed section l) just inadnected to the side bars of the frame Jar the supplemental bed sectionI) adjacent the forward ends thereof, and depending therefrom whenthe-bed section is in itsnormal positionrarc a'pair-of arms G G, thelower Tends of-.\vhich are connected by suitable pivot pins g g, saidpivot pins being coneniently extended laterally for a slig t dis- Lance.The projecting ends of the rear cross bars (2' of the bed section E restupon the edges of inclined rail members H- It which are secured to theinner surfaces of the sides of the open frame of the carto'iage B,adjacent the rear end thereof, sait rail members comprisin forwardlyinclined portions which extend rom the top to the bottom of the sides ofthe open frame of the carriage B and terminate at their upper ends inforwart ll extending horizontally disposed portions H, the upper edgesof which are positioned in substantially the plane of the upper edges ofthe sides of the open frame of the carriage B. Secured to the inner sur-.faces of the sides of the open frame of the carriage B adjacent thefront ends thereof are short supporting members T l. the up per edges ofwhich are positioned in suh-- stantially the plane of the upper edges ofthe sides of the open frame of the carriage B. With this construction,when the seat frame C is swung on its hinges to bring the bed section l5carried thereby uppermost, the links Ft will just be moved rearwardly ontheir pivots and the supplemental bed section I) will be raised in theopen frame of the carriage it. .\s the seat frame (I is swung over to ahorizontal position, the projecting ends of the front cross bar 1:thereof will be drawn onto the supporting members I l heretoforereferred to. During this movement of the supplemental bed sec.-

tion E the projecting ends of the rear cross piece c thereof will travelon therail incinhers ll .l] and will, when the bed section has beenmoved to its proper position. rest upon the horizontally disposedportions ll ll of said rail members. It will thus be seen that the. snp)lemental bed section is supported at; both its forward and rear ends onfixed supporting incmbers which are carried by the open frame of thecarriage B.

K designates the back of the sofa which isals-o adapted t constitnte thehead section -of the bed. The back K comprises a frame.

which is conveniently formed of angle iron, the side bars of which arebolted or ther wise secured, adjacent their lower ends. to a suitablecross piece. The frame tof the hack K is provided with a suitable springfabric which terminates at some distance from the lower ends of the sidebars: of the frame so as to provide sutlicient space to permit thepassage of the seat frame as the same is swung on its hinges. The lowerends of the sidebars of the frame of the back K are pivotally connectedin any suitable manner to supports k 15- which projectupwardly from thesides of the open frame of the carriage Badjacent the. rear end thereof.
